Product Overview
The SLD Tech ST-60Q-12CD is a 60 W monocrystalline solar panel with a nominal 12 V output. "Nominal 12 V" means the panel is built to charge a 12 V battery bank through a charge controller. Its working voltage (Vmp) is 19.08 V, which is higher than the battery voltage so the controller has room to charge.
The panel has 33 monocrystalline cells. SLD describes the construction as a heavy-duty anodized aluminum frame with low-iron tempered glass. It measures about 22.2 × 22.8 × 1.4 inches and weighs 3.95 kg (8.71 lb).
Best For
- Off-grid 12 V battery charging: Charges a 12 V battery bank through a charge controller.
- Off-grid uses SLD lists: SLD's product pages for its Q-series 12 V monocrystalline panels list traffic and safety, telecommunications and lighting among their off-grid applications. SLD doesn't publish a page for this exact model.
- Expanding an existing 12 V panel array: Add more 60 W panels of the same model to increase charging power (see the series and parallel limits below).
Key Features & Specifications
| Specification | Details |
|---|---|
| Product type | Monocrystalline solar panel |
| Model / manufacturer part number | ST-60Q-12CD |
| Rated power (STC) | 60 W. STC (Standard Test Conditions) is the lab test used to rate every panel the same way. |
| Nominal output | 12 V (for charging a 12 V battery through a charge controller) |
| Voltage / current at max power (Vmp / Imp) | 19.08 V / 3.16 A |
| Open-circuit voltage (Voc) | 22.35 V at STC. This is the panel's voltage with nothing connected. It goes up in cold weather. |
| Short-circuit current (Isc) | 3.36 A at STC |
| Temperature coefficients | Pmax −0.38%/K; Voc −0.36%/K; Isc +0.07%/K. Power drops a little as the panel heats up, and voltage rises in the cold. |
| NOCT | 47 ± 2°C (nominal operating cell temperature, for reference) |
| Operating temperature | −40°C to +85°C |
| Maximum system voltage | 600 VDC |
| Solar cells | 33 monocrystalline cells (11 × 3) |
| Dimensions | 565 × 580 × 35 mm (22.24 × 22.83 × 1.38 in) |
| Weight | 3.95 kg (8.71 lb) |
| Construction | Anodized aluminum frame; low-iron tempered glass (as described by SLD) |
| Warranty | 1-year limited warranty on materials and manufacturing and a 5-year workmanship warranty (panels under 100 W), per SLD's Warranty & Policy page (last updated April 29, 2026). SLD's datasheet also lists a 5-year product workmanship warranty. |
What You May Also Need
Usually required
- Solar charge controller: Sits between the panel and the battery and controls charging. Choose a controller rated for your battery voltage and for this panel's Voc and Isc. SLD's installation manual (May 31, 2023) says to multiply the panel's Isc and Voc by 1.25 when sizing connected equipment, conductors and fuses.
- Battery bank: A 12 V battery bank stores the energy for use when the sun is down. Battery chemistry and charge settings must match the controller.
- Mounting hardware: Holds the panel at the right angle. For roof or flat-roof installs, see rails, tilt legs, module clamps and roof attachments. For a pole or wall mount, choose one rated for this panel's size and weight. Choose clamps or bolts that fit this panel's 35 mm frame.
May be required
- Cables and wiring: Wire from the panel to the controller. SLD's documents for this model do not name the connector type, so check the connectors on the panel you receive before buying extension cables.
- Disconnects and breakers: Fuses or breakers between the panel, controller and battery protect the wiring and let you isolate the system for service.
- Grounding hardware: SLD's installation manual (May 31, 2023) recommends earthing (grounding) the frame, even though the modules are safety class II. It says to use a serrated washer or self-tapping screw to cut through the anodized coating, and that a qualified electrician should make the connection.
Optional upgrades
- Additional matching panels: More panels of the same model add charging power. SLD's installation manual (May 31, 2023) recommends no more than 3 panels in parallel. How many panels you can wire in series is limited by this panel's 600 V maximum system voltage, its open-circuit voltage (Voc) at your site's coldest temperature and your charge controller's input limit. Size strings per the NEC and SLD's datasheet.
- Battery monitor: Shows battery state of charge and charging current so you can see how the system is performing.
Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.
Important Considerations
- Mounting. SLD's installation manual (May 31, 2023) says to fasten each panel at a minimum of 6 points on the long sides of the frame, never by the short sides. Use the existing frame holes; SLD says drilling additional holes voids the warranty.
- Cold-weather voltage. Voc rises as temperature drops. When wiring panels in series, check that the total voltage at your site's coldest temperature stays under the controller's limit and the panel's 600 V maximum system voltage.
- Matching panels. SLD's manual says panels in series must have the same current rating and panels in parallel must have the same voltage rating.
- Location. SLD's installation manual (May 31, 2023) says the panels are intended for temperate climates and must not be installed near highly flammable gases or vapors. It recommends installing at least 500 m from the sea because of corrosion risk.
- Qualified installer. SLD's manual says installation, setup, maintenance and repairs must be carried out by qualified and authorized persons.
